Section 194 of the Legal Services Act 2007 provides for pro bono costs orders in civil courts, tribunals and settlement agreements. They are just like ordinary civil legal costs, but where a party was represented for free in relation to proceedings.
They require the losing party to pay costs to the Access to Justice Foundation, which uses these funds to support the provision of free legal help to those in need."
It seems, from what joshy said, the lawyer reached out to him. Maybe to try and scoop up the costs from whatever lolsuit joshy has in mind. If the guy isn't doing it for publicity (I'm not going with the "threat to safety" bit), then it's got to be money.
